    摘要: A system may comprise a first node that includes an ordering point for data, the first node being operative to employ a write-back transaction associated with writing the data back to memory. The first node broadcasts a write-back message to at least one other node in the system in response to an acknowledgement provided by the memory indicating that the ordering point for the data has migrated from the first node to the memory.

    摘要: Systems and methods are disclosed for interaction between different cache coherency protocols. One system may comprise a home node that receives a request for data from a first node in a first cache coherency protocol. A second node provides a conflict response to a request for the data from the home node. The conflict response indicates that an ordering point for the data is migrating according to a second cache coherency protocol, which is different from the first cache coherency protocol.

    摘要: A system includes a first node that broadcasts a request for data. A second node having a first state associated with the data defines the second node as an ordering point for the data. The second node provides a response to the first node that transfers the ordering point to the first node in response to the request for the data.

    摘要: Systems and methods are disclosed for blocking data responses. One system includes a target node that, in response to a source broadcast request for requested data, provides a response that includes a copy of the requested data. The target node also provides a blocking message to a home node associated with the requested data. The blocking message being operative cause the home node to provide a non-data response to the source broadcast request if the blocking message is matched with the source broadcast request at the home node.

    摘要: A system comprises a first node including data having an associated state. The associated state of the data at the first node is a modified state. The system also comprises a second node operative to provide a non-migratory source broadcast request for the data. The first node is operative in response to the non-migratory source broadcast request to provide the data to the second node and to transition the associated state of the data at the first node from the modified state to an owner state without updating memory. The second node is operative to receive the data from the first node and assign a shared state to an associated state of the data at the second node.

    摘要: A system comprises a first node that provides a source broadcast request for data. The first node is operable to respond in a first manner to other source broadcast requests for the data while the source broadcast for the data is pending at the first node. The first node is operable to respond in a second manner to the other source broadcast requests for the data in response to receiving an ownership data response at the first node.

    摘要: A system comprises a first node including data having an associated D-state and a second node operative to provide a source broadcast requesting the data. The first node is operative in response to the source broadcast to provide the data to the second node and transition the state associated with the data at the first node from the D-state to an O-state without concurrently updating memory. An S-state is associated with the data at the second node.

    摘要: Multi-processor systems and methods are disclosed that employ speculative source requests to obtain speculative data fills in response to a cache miss. In one embodiment, a source processor generates a speculative source request and a system source request in response to a cache miss. At least one processor provides a speculative data fill to a source processor in response to the speculative source request. The processor system provides a coherent data fill to the processor in response to the system source request.

    摘要: A system comprises a first node that provides a broadcast request for data. The first node receives a read conflict response to the broadcast request from the first node. The read conflict response indicates that a second node has a pending broadcast read request for the data. A third node provides the requested data to the first node in response to the broadcast request from the first node. The first node fills the data provided by the third node in a cache associated with the first node.
